Psychology & PsychiatryThu, 23 Feb 2017 07:12:55 EDTnews407056364How many types of neurons are there in the brain?For decades, scientists have struggled to develop a comprehensive census of cell types in the brain. Now, in a pair of companion papers, researchers at Columbia's Mortimer B. Zuckerman Mind Brain Behavior Institute describe powerful new approaches to systematically identify individual classes of brain cells, or neurons, in the spinal cord. In doing so, they reveal elements of the underlying circuit architecture through which these neurons shape movement—and highlight how statistical approaches could provide neuroscientists with a critical tool to quantify the cellular diversity of any region of the brain.https://medicalxpress.com/news/2016-03-neurons-brain.html

HealthFri, 12 Apr 2013 11:30:57 EDTnews284985050Optimal evidence accumulation in decision-making(Medical Xpress)—At the same settings and light conditions, a camera will take the same picture every time. In contrast, a brain does not make perfect reconstructions of a stimulus. It appears instead to accumulate evidence over time, which it then fits to an evolving internal model. A group of Princeton researchers has sought to explain some aspects of how rats and humans might accumulate evidence in an experimental decision-making task. Publishing recently in Science, they present a method which they claim can reveal internal properties of the decision processes in the absence of any details about how that accumulator works. They further conclude that the accumulator, the memory of the rat or human subject, operates with zero noise.https://medicalxpress.com/news/2013-04-optimal-evidence-accumulation-decision-making.html
